When we talk about dominant female world champions few can match the dominance of Japan's Momo Koseki (17-2-1, 4) pictured.

Koseki, the WBC Atomweight world champion, hasn't lost a fight since since November 2007 and has not become a world champion but become a dominant one defending her title an impressive 12 times since August 2008. Yes you read that right, Koseki has defended her world title 12 times in less than 6 years and what's more impressive is that she's been doing it against some top opposition such as Teeraporn Pannimit Masae Akitaya and Saemi Hanagata.

Tough as old boots, aggressive and well schooled Koseki is a nightmare to fight. She can go to war with you, she can rough you up or she can box with her well schooled skills. Their are flaws in her style, of course there are, but they tend to revolve around the way she comes in with her head as opposed to things that would make it easier to beat her. She's a really tough opponent and she has experience to go with her skills.

Attempting to prevent Koseki from her 13th title defense on March 3rd will be unbeaten Thai Angor Onesongchaigym (5-0, 3) who we believe is a teenager.

Angor may not have the record of an experienced fighter though we're of the belief that she is a highly established former Muay Thai fighter with more than 60 wins. Whilst it's true that not all great Muay Thai veterans become great boxers there is enough of a track record to suggest that Angor may be a very, very good fighter and the sort of fighter who could be a real banana skin for someone like Koseki.

Unfortunately it's very hard to be too sure about Angor with details on her being difficult to find. As with many lesser known Thai's footage of her is scarce and our recollection of fights of her that we've seen have all been her against very limited foes. She has looked decent admittedly but against the opponents she's been up against it's hard to really say anything about how she copes when hit back or what she does against more skilled foes.

With Koseki having a track record at world level, a long unbeaten run, plenty of footage out there and a very strong amateur background it's hard to suggest anything but another successful defense for the reigning champion. We do expect this to be a hard one, top Muay Thai fighters are known for their toughness and fighting ability, but we think that Koseki may just have too much boxing knowledge for Angor.

We're hoping that the winner here fights the WBA champion in a major Atomweight unification bout. Unfortunate that's something we've wanted to see for a while so aren't expecting it despite really wanting to see it.
